CONTROLLING DEVICE.

Specification of Letters Patent.

Patented Mar. 22, 1910.

Application filed August 31, 1909. Serial No. 515,393.

To all whom it may concern: I

Be it known that I, Ross V. INGLISH, a citizen of the United States, and a resident of Alpena, in the county of Alpena and State of Michigan, have invented a new and Improved Controlling Device, of which the following is a full, clear, and exact description.

The invention relates to pulp or paper machines, and its object is to provide a new and improved controlling device for controlling the flow of'pulp into the paper machine with a view to supply the latter with the proper amount of pulp for the correct working of the machine, and to insure a steady flow of the pulp without danger of clogging.

For the purpose mentioned, the controlling device is arranged in the feed pipe of the paper machine, and consists essentially of two perforate members adjustable one relative to the other, to control the amount of pulp flowing through the opposite perforations.

A practical embodiment of the invention is represented in the accompanying drawing forming a part of this specification, in which the ligure is a sectional side elevation of the improved controlling device.

A suitably constructed casing A, is provided with an inlet pipe B, and an outlet C having a pipe D, leading to the paper machine to be supplied with the pulp. Through the casing A extends a vertically disposed shaft E, connected at its upper end by belt and pulleys or other means with other machinery, for imparting a continuous rotary motion to the shaft E. The lower end E of the shaft E is set on the pointed end F of a screw F, screwing in the bottom cap C of the outlet C, and on the outer end of the screw rod F is secured a hand wheel F under the control of the operator, for turning the screw F with a view to raise or lower the shaft E.

On the shaft E within the casing A is secured a disk G, from which depends a cylindrical member G, rotating within a similar member H, attached at its lower end to a disk H, screwed or otherwise fastened to the upper end of the outlet C. The members Gr and H are provided with apertures G H of conical shape, with the apex ends opposite each other, as plainly indicated in the drawing, the apertures G being in more or less registering position relative to the apertures H according to the adjustment given to the shaft E and the disk Gr carrying the member G. Now when the control ling device is in use, the member G rotates within the member H, and the amount of pulp passing through the registering apertures H and G can be governed by the operator turning the hand wheel F to raise or lower the member G relative to the member H.

The disk G is provided with depending rods I, having agitating arms I, extending within the casing A exteriorly of the member H, so that when the device is in use and the shaft E, disk G and member G are rotating, then the agitating arms I keep the pulp stirred or agitated in the casing A, to prevent clogging and hence to insure a proper flow of the pulp through the registering apertures H and G By making the apertures G and conical with the apexes opposite, the pulp is not liable to clog during its passage through the registering apertures.

Agitating links J are secured to the shaft E within the outlet C, so as to keep the pulp agitated oppositeflthe pipe D, to insure the proper flow of the pulp to the machine.

The controlling device shown and described is very simple and durable in construction and not liable easily to get out of order.

Although I have shown manually controlled means for raising and lowering the shaft E and the member Gr, it is evident that automatic means may be employed and controlled from the paper machine for the same purpose.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A controlling device in the feed pipe of a pulp or other machine, comprising two perforate members arranged across the flow of the pulp, one of the members being revoluble and adjustable relative to the other member to govern the amount of the pulp passing through the device.

2. A controlling device in the feed pipe of a pulp or paper machine, comprising a fixed perforate member, a revoluble perforate member, and means for adjusting the members one relative to the other.

3. A controlling device, comprising a casing having an inlet and an outlet, at perforate member fixed in the said casing, a perforate revoluble cut-0E member for the said fixed member, and means for adjusting the said cut-off member relative to the said fixed member.

4. A controlling device, comprising a casing having an inlet and an outlet, a cylin drical perforate member fixed in the said casing, a perforate revoluble cut-off member for the said fixed member, and means for adjusting the revoluble member axially.

5. A controlling device, comprising a casing having an inlet and an outlet, a cylindrical perforate member fixed in the said casing, a perforate revoluble cut-off member for the said fixed member, means for adjusting .the revoluble member axially, and an a itating means attached to the said revoluble member.

6. A controlling device, comprising a casing having an inlet and an outlet, at cylindrical perforate member fixed in the said casing, a perforate revoluble cut-off member for the said fixed member, means for adjusting the revoluble member axially, and agitating means attached to the said revoluble member and extending outside of the said fixed member.

7. A controlling device, comprising a casing having an inlet and an outlet, a cylindrical perforate member fixed in the said casing, a perforate revoluble cut-01f member for the said fixed member, means for adjusting the revoluble member axially, and agitating means attached to the said revoluble member and arranged in the outlet of the casing.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

ROSS V. INGLISH.
